CUSHION CONSTRUCTION.

To all whom it may concern:

Be it known that I, FRED A. NACHMAN, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and'useful Improvementsin Cushion Constructions, of which the following is a specification.

This invention relates to improvements in cushionconstructions, and is more particu larly related to cushions of a loose or port able character as distinguished from those built into and made a partof rigid structures. i

The object of the present invention is to providea structure which,includes as the basic resilient feature a plurality of spring units properly related to impart the requisite yielding to the weight imposed thereon, but which are so separated with respect to each other as to preclude overlapping or nesting of the coils employed in the units,

thereby preventing interference in the motion of the contiguous springs and likewise.

wear on the 'tex'-t1le covering of the springs incident to their proximity with each other.

A further object ofthe invention is to so construct a cushion as to render the same substantially noiseless in its action under the weight to which it is subjected, andto so arrange and relate the minimum amount of material isnecessary t produce the cushion.

The. invention also seeks to provide a novel form of spring unit for incorporation in the cushion which will permit the. ready use of the unit in any length or numbers without impairing the integrity or ada tability of the individual springs and t eircoverings. 40

accompanying drawings, set forth in the following description, and the novel features thereof are defined in the claims hereto ap' pended.

In the drawings:

Figure 1 is a to(p plan view-of a cushionconstruction embo ing the hereincl'escribed invention partly in section.

Fi 2 is an end elevation thereof, also part y in section.

panying drawings, the, numeral 10 desigparts that only a The invention is an illustrated in the' Fig. 3 1s a transverse sectional view, taken formed of a suitable textile fabric 13, which may be muslin, each pocket bein closed at one of its ends and open at the ot er for the introduction of the particular spring coil which is to be incased thereb After the coils are introduced into t e respective pockets the entire length of the fabric is stitched along a longitudinal line, defined I Specification 01 Letters Patent.

by the numeral 14, and the coils aregthus confined within the. several, pockets or cells. The fabric from which the pockets are formed is provided with vertically-extending rows of stitches-15 arranged in pairs,

and these rows of stitches form the'several pockets or cells, but interposed between the stitches of each pair is a webbing 16 which provides aconnecting medium between the ockets and also permits severance of the StIflpbf pockets at any desired point. By means of this expedient any number of,

adjacent the incased coils may be taken from the strip as occasion may require without impairing the integrity of any individual ocket, and the s ring units therefore may e'made of any ength and to include any number of the coils which shall be essential in producing the various sizes of cushions.

To construct a cushion of the dimensions required, the units are arranged in the parallel relation previously referred'to, and more particularly illustrated in Fig. 1. In so assembling the units a layer 17 of cotton felting, or other suitable 'material,*. is arranged between the contig'uous. units in.

parallel relation therewith, said filling extending between said units throughout their length, and the to and bottom ends of the several spring coi s are tied to the respective top and bottom ends of the immediately contiguous spring coils as at 18. These'ties equivalent material and they penetrate the j 18 are preferably formed of stout twine orfilling layer 17 so that the la'yer and the coils are thereby bound together. Thefties eff factually hold the contiguous coils immediately opposite each other and prevent them overlapping or nesting into the spaces between the coils of the adjacent units. At

the same time in the applieationtof these ties the filling layer 17 is compressed tosuch an extent. immediately between the code that the portion of the layer which is in the interstices between the coils readily ex ands into these intersticesa-nd thus fills the utter. Iiy reason of this, the expanded portions of the layers 17 tend to prevent. any swerving of the coils from their positions op osite to the-coils to which they are tied, an also reduce the noise incidental to the working of the coils under't-hc superimposed weight to a. minimum.

Surrounding the body of the cushion as formed by theparallelunits deseribedis a seriesof mar ina-l coils 19 which are formed in precisely the same way as the other coils and units, that is to say, as a connected strip, butthese'lninrginal coils are of less height than the body coils and thus give to the edges of the cushion a more symmetrical appearance. These marginal coils also serve to prevent the formation of sharp edges at the side portions'of the cushion and give to the-cushion a neutral ertion which is raised in relation to such sire port-ions. The ends of theso'eoils are tied to the ends of'the immediately adjacent coils of theXbody units hy'tics 2t) whirli are the sauwin construe tlon and appliratiou as the tire 18. The

marginal series 19 alsoprecludes the news sity of any binding hands or irons, which are commonly in use in portable cushions of this rharactor.

The col-.slriu-tinn herein dvsnribel'l whilr slwriiirally referred to in connection with oushion ronstrurlions is obviouslyadapted for use in the construction of mattresses.

it will also hemln'ious that, with the units assembled in the manner dost-rilwd. to (our plnl'ea cushion the assembled units will be l wlfitorod by inclosiug the same in the usual casing and filling the var-in al ihe appropriate points with suftmaterialsuch as cotton hair and the like, is 'eoi-nmouly emph yed. Having ll'lllsxllt fitfl'llmtl the ll'lVQuLlUlL what isr-lainu'dlns new-and desired to be Su- ".r ureil by Letters-'- Patient; is:

1; A. ronsiifl'f-tion of the class describe-d.

comprising a plurality of pocketed springs arranged in rows, the springs of each row bemgdirectly opposite the sprin s of contiguous rows, a yieldin filling interposed between the sprin s of the contiguous rows, and ties connectec to the opposite springs and also those portions of the interposed filling directly between the opposite springs and compressing the filling at such points, the ortions of the filling intermediate the ties eing expanded into the inteiz tices between the springs and filling the same.

'2. A construction of the class described, romprisin ai plurality of spring units each of which consists of aveonnectud series of pocketsalid-springs incased by said pcwlcets compressible yielding layers interposed be tween said llllllr-l and serving to separate the springs of each unit from the springs of the units. immediately contiguous lhvrrlo, the springs of the units being opposite each other, and ties penetrating the unit. and tho interposed filling and binding together the opposite springs of contiguous units to preserve them in opposite relation hut separated from contact with oaeh other, those portions of the filling inn-rnualiatc silltl ties being c.\'- panded into the interstices between the coils of the respective units to lill such interstices.

constructionof the class described, comprising-a plurality of pocketed springs arranged in parallel rows and forming body units; a filling ii'n'erposed between eontiguous. rowsof said pockotiul springs to maintain the latter. in separated relation] and prerrnt their roulact a commuted series of pocket-ed springs surroum'ling said body units and forming a marginal unit. said marginal springs hein; of lvssheigrl-it than the body springs. ties ronuucting i-outiguous body units and penetrating the lillvliurr'lul lilliin, to compress the latter and to hold the units in opposite relation to rm'liotluu" and means for connecting the marginal unit to said-body units.
